How to Checkmate with Bishop and Knight

This video demonstrates how to checkmate with the bishop and knight. After some experimentation with solving the bishop and knight checkmate, I found that the first step of simply centralizing ones pieces on the four center squares, with the knight on the same color square as the bishop, is an efficient coordination of the pieces. The knight from such a position is then very quick to becoming optimized in what follows of the Deletang's Triangles, where the king is forced into a large triangle, a medium triangle, and then a small triangle. Once the king is in the small triangle and restricted to exactly two squares, we give checkmate. Practice makes perfect!
